00:01 Hello, in this question, since the magnetic field is 0 .470 tesla and the r, that is the radius, is 74 cm, which we can write 0 .74 meters.
00:16 And as we know, mass of proton is 1 .673 multiplied by 10 .27 for minus 27 kages, right? it is very less.
00:26 So by balancing the forces, the centripetal force mv squared by r equals the magnetic force that is qvb, right? so from here, v equals qrb by mass of proton...
